10. 2 Passes and a Husband
I saw this on Gilmore Girls and I've played, it's fun!
You and a friend spot the first stranger to walk by, you either take him or pass and wait for the next.
You can either marry him or pass.
If you pass twice you're stuck with the third guy no matter what.
Now you can get creative while you're watching people walk by!
What other games have you played with people watching?
